Audio Amp - Headphone - Pi Zero W

Purchased headphone Audio Amp
Installed on Pi zero W
Using Raspbian Lite Bullseye

Script still sets Music directory as user pi ← Have changed to my account
Running proceeds apace

user mopidy <00 does not gain correct read permission
mopidy service runs find at system level
/etc/mopidy is not created
Screen is not initialised

In essence the whole installer seems to be broken with regards to the Bullseye release and running on a pi zero W

can anyone provide some insight into this at all?
